Similar advice that's no doubt been asked here about mini exhausts. I have a bog standard TRX850 with standard pipes, and want to put some more fruity cans on the back. I have seen the below custom fit ones:

Some guys have whacked bigger cans with no baffles in them, sound great, but not sure if its good for the breathing / back pressure of the engine. Whats the general rule? Better for same size pipe from cylinder head to silencer, or bigger silencer so allow more gas out? Clearly would not go smaller, its a 4 stroke parallel twin engine.
Any advice greatly received!
